Basilika Maria Dreieichen, Baroque parish church in Rosenburg-Mold, Austria.
Basilika Maria Dreieichen is a baroque pilgrimage and parish church set on a hill above the Horn Valley in Rosenburg-Mold, Lower Austria. It has two towers that stand out over the valley, and the interior features altars, frescoes, and stucco work typical of the baroque period.
The church was built in 1744 to designs by architect Leopold Wißgrill, replacing an earlier chapel that had drawn pilgrims since the 17th century. Shortly after completion it was granted basilica status, which established it as one of the main pilgrimage sites in Lower Austria.
The name of the site refers to three oak trees that once stood on this hill and are said to have sparked Marian devotion here. Pilgrims from across the region still come on foot to pray at the church, keeping a living tradition on the hillside.
The church sits on a hill and can be reached on foot or by car along a side road. Visiting on a quiet weekday gives more space to move around inside and take in the details without crowds.
At the foot of the hill there is a spring known as the Maria well, which was considered sacred even before the church was built. Many pilgrims still visit it as a fixed part of their journey to the site.
